Description of Some Restorative Materials

 

Full Contour Zirconia-ie:Bruxzir, Zirlix FC
  • Single crowns and all bridgework

  • Conservative prep Ok minimal 0.5 mm occlusal clearance.

  • Adhesive or conventional cementation, follow cementation guides for zirconia; specific cleansing of the interior of crown after try in is required. Adhesive advised for short preparations.

This is a solid, monolithic zirconia material. The zirconia used is more translucent than that used in substructures.  These zirconia restorations are manufactured using CAD/CAM technology. They can be created using scans from a traditional cast or from an intraoral scan. The surface is stained, glazed and polished. This material is very strong and abrasion-resistant; adjusting is difficult but possible chairside. Efforts should be made to communicate accurate occlusal records.

 

The design may be modified so as to permit layering with esthetic ceramics on the facial surface. This modification might be used in a clinical situation where traditionally a metal occlusal or lingual PFM would have been employed. This is a very esethic restoration. Bruxzir is a branded material marketed by Glidewell lab which licenses others to manufacture it. Zirlux FC is a Henry Schein product.  There are other companies that provide their own monolithic zirconia materials, each touting their own benefits.

 

PFZ Porcelain Fused to Zirconia ie: Lava
  • Single or multiple units up to 10 units with a maximum of 2 pontics.

  • Champher or shoulder preparation with 1.5- 2.0 mm reduction

  • Adhesive or conventional cementation, follow cementation guides for zirconia; specific cleansing of interior of crown after try in is required.

These are zirconia frameworks manufactured using CAD/CAM technology. They can be created using scans from a traditional cast or from an intraoral scan. The framework is veneered with feldspathic ceramic material. These restorations can be very esthetic and can mask to some degree discolored preparations. Stump shade should be recorded and communicated to the laboratory at commencement of case. Lava ia a 3M product.

 

Emax CAD Full Contour
  • Single anterior or posterior crowns, anterior bridges with one pontic.

  • Created using CAD/CAM technology using scans from casts or intraoral scans.

  • Champher or shoulder preparations with 1.5 mm occlusal reduction and 1mm axial reduction as minimal.

Adhesive or conventional cementation

These are monolithic lithium disilicate restorations. They are glazed, stained, and polished. Strong and reasonably esthetic. Available in varied opacities to mask substrate, stump shade should be recorded and communicated to the laboratory at commencement of case.E Max is an Ivoclar material. This is an Ivoclar material.

 

EMax CAD Layered
  • Single anterior or posterior crowns, anterior bridges with one pontic.

  • Created using CAD/CAM technology using scans from casts or intraoral scans.

  • Champher or shoulder preparations with 1.5 mm occlusal reduction and 1mm axial reduction as minimal.

Adhesive or conventional cementation

These are the same as the full contour except that they are not monolithic, that is they have a veneering material fused over a core material. This esthetic ceramic veneer can cover all or part of the restoration to meet the specific needs. They are available in varied opacities. Stump shade should be recorded and communicated to the laboratory at commencement of case. This is an Ivoclar material. 

 

EMax Pressed Full Contour and Layered
  • Thin and traditional veneers. Single anterior or posterior crowns, anterior bridges with one pontic.

  • Created using ceramic press technology.

  • Champher or shoulder preparations with 1.5 mm occlusal reduction and 1mm axial reduction as minimal. Veneers 0.6 gingival shoulder.

Adhesive or conventional cementation crowns, adhesive for veneers.

These lithium disilicate restorations are similar to EMax CAD however the processing is different. These are pressed ceramics using the lost wax process. This version is EMax is slightly stronger and can be used for veneers and small bridges. Just as with EMax CAD these can be made full contour or layered for a more esthetic result. This is an Ivoclar material.

 

Emax Cad-on
  • Single units and 3 to 4 unit bridges

  • Champher or shoulder prep

  • Adhesive or conventional cementation

These restorations are created using CAD/Cam technology. They are composed of a Zircad zirconium framework and an Emax Cad veneer. Both components are designed at the same time , milled separately and then fused together. Layering of ceram material is not possible with this technique however characterization is possible with the use of surface stains. This in an Ivoclar material.

 

Layered Feldspathic Veneers
  • Veneer restorations

  • Champher preparation

  • Adhesive cementation

These veneers are the traditional processing method. Created by stacking feldspathic ceramics on a refractory die or platinum foil matrix. These are highly esthetic restorations. Stump shade is critical and opacities can vary even within the same tooth. Photos of preps are helpful.

 

Lava Ultimate
  • Single crowns, inlays, onlays and veneers

  • Minimal Champher preparation

  • Adhesive cementation

This is resin nano ceramic CAD/CAM material, which is polished not heat glazed. It can be characterized with photo curing stains. Said to add a shock absorber to implant restorations due to its elastic modulus that is comparable to dentin. These can be created from intraoral scans as well as traditional impressions. Lava Ultimate is a 3M material.

 

Vita Blocks
  • Single crowns and veneers

  • Champher preparation

  • Adhesive cementation

These are feldspathic ceramic blocks milled using CAD/CAM technology. They can be created using intraoral scans or scans of the dental casts. Very esthetic material and alterations can be accomplished using layering ceramics and stains.

 

Captek
  • Single crowns and bridges

  • Same preparation as for a PFM

  • Adhesive or conventional cementation

Captek™ is a unique material with unique qualities, unknown in any other dental material. It is composed of only high noble metals such as Gold, Platinum and Palladium. Its unmatched composition and structure allows Captek™ to exhibit characteristics that are exclusive to it. Captek substructures can now be created usinf CAD/CAM technology. Feldspathic ceramic is layered over a Captek substructure. See Capek.com or call me for more information.

 

Tilite Base Alloy

Tilite alloy is a base alloy which may be used for all types of cast and pfm restorations. It is manufactured by Talladium and they refer to it as “The first and only medically pure base alloy with titanium”. This alloy handles very nicely in the laboratory. I have not experienced any discoloration or bond issues. You may call me for more information on this material or you can contact the manufacturer –Talladium Inc.
